I am not a current grower but here are a few personal observations.... Sour cherry trees are much more cold hardy and less prone to disease. Sweet cherry trees are more prone to infestations by insects, such as the cherry fruit worm and cherry aphids. Apply a horticultural oil during the dormant season and a fungicide in the spring to ward off diseases. Cover trees with netting while the fruit ripens... to thwart the birds.A sweet cherry tree might not bear fruit for at least five years. Unlike sour cherry trees, sweet cherries are not self-pollinating. You must plant two different cultivars to get adequate pollination and harvest. Yes, it can be another dwarf cultivar with a similar blooming time. Plant sweet cherry trees within 100 feet of each other, choose trees with similar bloom times (for pollination purposes) and avoid using pesticides in the garden, which might kill the honeybees needed for pollination. Sweet cherries are generally larger, and a lighter red and their pulp is thicker/firmer, a cream-yellow color on the inside. The fruit of sweet cherry trees usually looks more heart-shaped versus more rounder for sour cherries.
